Diabetes Mellitus 2-3% of the population. The disease
can be characterised by five main symptoms,
an inability to reabsorb water, causing increased urine
production, excessive thirst, excessive hunger, and a gross fluctuation in
weight with a loss of energy. Drowsiness can occur and a feeling of hunger
can be so pronounced even after a large meal. There are 2 types of
diabetes. Type I and Type II. Type I is insulin dependant. It is the most
severe form and can often occur in individuals under the age of 35. Type
II is more common affecting 90% of all diagnosed cases, it normally occurs
in people who are over forty and are either overweight or obese.
There may be no symptoms at all, in mild cases, but
most diabetics are more susceptible to slight infections. The worst
symptoms can be loss of sensation (Neuropathy) and inadequate circulation
(Ischaemia). There is still a partial ability to secrete insulin and the
high glucose levels in the blood can usually be controlled with a
combination of diet and drug therapy. This type of diabetes is gradual,
but is invariably accentuated by over-eating, drugs or shock. Type II
diabetes will tend to have all the symptoms and dangers involved with
people who have type I diabetes, but the cases are milder.
Ischaemia can directly attribute to inadequate
circulation and tissue oxygenation, poor wound healing, a susceptibility
to infection, ulceration and gangrene. Shoe pressure can cause tissue
damage. When infection is present in legs and feet this can cause a
vasoconstriction which compromises the flow of blood and lymph supply to
the area, this can result in infections which can spread. This is a
diabetic ulcer and it is slow to heal and amputation cannot be ruled out
if not caught early.
Venous ulcers are severe. They usually affect the ankle
joint, (malleolus), and is accompanied by significant oedema (swelling).
Arterial ulcers are very deep, painful and gangrenous and are normally
situated on the foot and the shin.
Regular visits to a chiropodist, to remove callouses,
corns, etc is important, as is the general cutting of nails. Your visit
will also be an opportunity to have your feet checked thoroughly for
foreign bodies or changes in your skin tone and to discuss any problems
you may have.
People with diabetes should have their feet examined
every year as part of their medical check so that any changes can be noted
and advice given about special care. They should be encouraged to give up
smoking and to keep their blood glucose levels well controlled and eat a
healthy balanced diet. They should take regular exercise. They should
protect their feet from extremes of temperature and wear well fitting
socks, stockings, tights and shoes. Always check shoes for sharp objects
before putting on.
People with diabetes should be encouraged to examine
their own feet every day, checking for signs of callus or breaks in the
skin. If they cannot do this for themselves they are encouraged to find
someone else to do this for them. They are advised to look for anything
suspicious such as change in colour of skin, swelling, pus, or any change
in movement. They must not treat any problems themselves but to seek help
immediately from their G.P. Specialist nurse or chiropodist.
